CULTIVATOR.

To all whom it may concern.'

Be it known that we, BENJAMIN F. LUKE and CHARLES. L. ALLEN, citizens ofthe United States, residing at Orangeville, in the county of Emery andState of Utah, have invented new and useful Improvements in Cultivators,of which the following is a specification.

Our present invention pertains to cultivators; and it consists in thepeculiar and advantageous cultivator, hereinafter described and claimed,designed more especially for working the ground adjacent the trunks oforchard trees where the low hanging limbs interfere with the use of anordinary cultivator.

In the drawings, forming part of this specification: Figure 1 is a planview of a cultivator constituting one embodiment of our invention. Fig.la is a detail inverted plan illustrating the lever on the underside ofthe pole, which lever is designed for the attachment of draft animals,and also illustrating certain parts connected to said lever. Fig. 2 is avertical longitudinal section taken on the line 2 2 of Fig. 1, lookingin the direction indicated by arrow. Fig. 3 is a detail rear elevation,partly in section, and showing the attachment of a group of weeders tothe rear portion of the main frame. Fig. 4 is a detail longitudinalvertical section illustrating the means for extending and ret-ractingthe plow-carrying bar of the machine. Fig. 5 is a detail planillustrating the manner in which a group of weeders or other cultivatingblades may be attached both to the outer portion of the plow-carryingbar and the main frame of the machine. Fig. 6 is a detail perspectiveshowing two of the weeders and the bar by which the group of weeders iscarried. Fig. 7 is a perspective illustrating a corrugator, a number ofwhich may be used in lieu of the weeders when occasion demands. Fig. 8is an elevation showing another cultivator blade, a plurality of whichmay be used in lieu of the weeders. Fig. 9 comprises disconnectedperspective views of still other blades adapted to be used in lieu ofthe weeders.

Referring by letter to the said drawings, and more particularly to Figs.1 to 4 thereof: A is the tongue of our novel machine. B is the axle uponthe end portions of which Specification of Letters Patent.

ground wheels C are loosely mounted. D is a horizontally swinging lever,pivotally connected at a to a pin carried at'one side of the tongue Aand arranged to swing horizontally in a plane below the tongue. E is aclevis pivotally connected to said lever D and designed to carry adouble-tree (not illustrated), and F is a tractile spring, connected atb to the underside of the tongue A, and at c to the lever D, and havinga tendency to draw the free end of the said lever forward. It will alsobe seen by comparison of Figs. 1 and 2 that the tongue A is equippedwith a drivers seat d, a segmental rack e, and a vertically swinginghand lever f, which hand lever is provided on its lower arm with arearwardly extending portion g, Fig. 2, and is equipped on its upper armwithl a detent 7L, designed to coperate with the segmental rack inadjustably fixing the lever in various positions. Fixed by shackles z',or other suitable means on the axle B, are the side bars G of the mainframe of the machine. The rear ends of the said side bars G areconnected by a cross-bar H lixed thereto, and a brace I has its ends jconnected to the side bars G and also has an intermediate portion Kconnected to the rear cross-bar I-I, the connections being rigid ones,and the purpose of the brace, as its name imports, is to lend increasedrigidity and strength to the main frame as a whole. The arms of the saidbrace I are connected together by a cross-bar J, and it will also benoted that one of the arms is connected to the adjacent side bar G by afixed transverse bar K, while the other arm of the bail is connected tothe adjacent side bar G by a transverse bar L. The forward ends of theside bars Gr are connected through the medium of a transverse rod M, andsaid ends are also connected to the depending portions m of a cross-barn, which cross-bar is ixedly connected by bolts p to the underside ofthe tongue A. Between the cross-rod M, at points adjacent the dependingportions m of the bar n, and the tongue, are interposed braces r. Therearwardly directed portion g on the lower arm of the hand lever f isconnected through a link s with the transverse portion J of the mainframe, and hence it will be manifest that when the upper arm of lever fis thrown forward the rear portion of the main frame will be raised,while when the upper arm of said lever f is moved rearward, the rearportion of the main frame will be depressed or moved downward. Fixed bybolts t to the tongue A and by a bolt .u to an arm o on the cross-bar n,is a bar N which extends outward to a point beyond one of the groundwheels C, and is provided at its outer end with a horizontally disposedsheave P, for a purpose hereinafter set forth. Suitably fixed on therear portion of the described main frame is a transverse bar Q in whichis a guideway L0 of inverted T-form in cross-section, as best shown inFig. 2. The said guideway wis designed to receive and guide thecorrespondinglyshaped extension bar R of our invention, in the directionof its length, and transversely or in the direction of the width of themachine. On it-s upper portion the said extension bar R is provided witha rack R2 which extends through a portion of its length, and

at its outer end the said extension bar is equipped with a horizontalsheave 1 a plow c, and a supporting wheel a2; the said supporting wheelbeing carried by a frame b2 having a stem 02 which extends up throughand is movable vertically and about its axis in a housing Z2 on theextension bar, and a coiled spring e2 being arranged in the housing cl2,and interposed between an abutment f2 on stem c2 and the upper end ofthe housing. It will be gathered from this that the spring is adapted tocarry the weight of the extension bar R and still permit of the plowbeing placed to move through the ground; also, that the stem c2 is freeto turn about its axis so as to enable the wheel to assume the correctposition when the machine is drawn forward after endwise adjustment ofthe bar R.

For the purpose of adjusting the bar R in the direction of its lengthand adjustably fixing the said bar in various positions, we provide themeans best shown in Fig. 4, which means comprises a suit-ably supporteddrum S having a pinion T intermeshed with the rack R, and also havingteeth U, a fixed segmental rack V, a hand lever W, suitably supportedand movable independently of the drum S, a detent X carried by the leverand adapted to engage the segmental rack V, and a detent Y2 also carriedbythe lever and adapted to engage the teeth U of the drum S. When thedetent X is held out of engagement with the segmental rack V, and

vthe lever W is moved in one direction with its detent Y2 in engagementwith the teeth U, the drum S and the pinion T will be rotated, and thebar R will be moved endwise outward or inward, according to thedirection of the said movement of the leverW. It will also be manifestthat after a movement of the lever W in one direction for the purposestated, its detent Y2 can be disengaged from the teeth U, and then afterthe lever is moved back to its original position and its detent Y2 isagain put in engagement with teeth U, a second movement of the lever inthe first-named direction will result in further endwise movement of thebar R, outward or inward, according to the direction in which the leverW is moved to rotate the drum. Then when the detent X is permitted toengage the segmental rack V, the drum S and its appurtenances will belocked against rotation and the extension bar R will be adjustably fixedin the position in which it is placed. At Z the drum S is provided witha circumferentially grooved portion. This grooved portion is designed totake up and pay off a cable A', preferably of wire, which is connectedto the said grooved portion and extends from the lower portion thereofaround the sheaves y and P, and is connected to the free end of thehori- Zontally swinging lever D hereinbefore referred to. Beingconnected to the drum S, it follows that when the said drum S is rotatedto move the extension bar R outward, the cable A will be fed off thecircumferentially grooved portion Z to an extent commensurate with theextension of bar R, while when the drum S is rotated to retract or drawthe bar R inward, a corresponding quantity of the cable A will be takenup on the drum or circumferentially grooved portion Z of the drum. Thusit will be manifest that at all times the cable A will take strain offthe extension bar R, and by reason of the connection of the said cableto the lever D adapted for the attachment of the draft animals, it willalso be manifest that the cable will equalize the draft, so that theouter portion of the extension bar R will be drawn forward as well asthe longitudinal central portion and other portions of the machine.

In the practical operation of our novel machine the plow z may be usedalone or may be used at the same time with a plurality of suitablecultivator blades, which latter may be connected to the rear portion ofthe main frame of the machine alone, as shown in Figs. 1, 2 and 3, orelse may be connected at one end to the extension bar R and at the otherend to the rear portion of the main frame as shown in Fig. 5. Thecultivator blades referred to are shown in Figs. 1, 2, 3, 5 and 6 asweeders. 1n the first mentioned instance the weeders are carried by abody bar C2, and this latter is connected by shackles D2 to lugs E2, onthe rear bar I-I of the main frame. In the secondnamed instance the bodybar C2 carrying the weeders B2v is connected by a shackle D2 to one ofthe lugs E2 on the frame bar H, this adjacent one end of the bar C2, andthe other end of the bar C2 is connected by a shackle D2 to a lug F2 onthe outer portion of the extension bar R. When the cultivator blades B2are carried in the manner last described, and as shown in Fig. 5, thesaid cultivator blades in common with the plow z, will pass freely underthe low hanging branches of orchard trees.

As before stated, the cultivator blades shown in Figs. 1, 2, 3 and 5,are in the form of weeders, and two of the said cultivat-or blades areshown in perspective in Fig. 6. l/Ve would have it understood, however,that in both of the instances mentioned the bar C2 may be equipped witheither corrugators B7, such as shown in Fig. 7 shovels B8, such as shownin Fig. 8, or blades B, such as shown in Fig. 9, in lieu of the weedersB2. In fact the cultivator blades used on the bar C2 may be of anydescription compatible with the purpose of our invention withoutinvolving departure from the scope of the invention as claimed.

Then the cultivator attachment is employed in the manner shown in Fig.5, the bar C2 will of course be attached after the extension bar R isplaced in the position desired, with respect to the main frame of themachine. When, however, the bar bearing the cultivator or ground-workingblades is connected in the manner shown in Figs. l, 2 and 3, the saidbar and the blades carried thereby will in no way interfere with theadjustment of the extension bar R as occasion demands.

l/Vhile we have shown and described certain forms of our invention, itis to be understood that we are not limited to the details or the formor relative arrangement of the parts disclosed, but that modificationsmay be made therein, without departing from the spirit thereof. Forinstance the bar R may be changed and made to extend from the right-handside of the main frame; the drum S, and pinion T and their appurtenancesbeing in that case mounted near the right-hand side of the main frame,between the auxiliary standard e3, Figs. 1 and 3, and the standard e,the latter having been shifted from the position shown to the righthandapertured bar K, Fig. 1. Therefore the term one side in our claims isintended to comprehend either side.
